Apparently, Rain and Kim Tae Hee aren't the only couple vacationing in Jeju Island!
Their agency, Saram Entertainment, stated on May 16,
"It is correct that the two of them are on Jeju Island. Honey Lee visited there because she also has filming on Jeju Island. Yoon Kye Sang likewise had personal business there, so he is at Jeju Island. Their schedule happened to overlap.
The two of them might naturally be mingling over there, but it is not correct to conclude that they went on a couple vacation. If I were to speak in detail, Honey Lee is currently 'busking' with friend Kim Ji Yeon on the gayageum (traditional Korean instrument)."
Still, we hope the two get to relax and enjoy the trip a bit together!
